car-wheels has been tested at Wilkes
barre, Pa. with satisfactory results.
By the old method three men could

perfect wheel every minute, or 720 per
day. One of the principal features Of
the new method is the use of steel
core, instead Of one of sand, in casting
the wheel. The core is removed by
knocking out center key, leaving the
hole perfectly true and ready to put
upon the axle at once. without dressing

500. 900. All this is of the most superior
quality, straight grained. and clear Of
knots and gnarls. To raise the tele-
graph poles of the countrp required
800. 900 trees. and 500. 900 more are re-
quired for annual repair. The railway
ties of the country annually consume
$1,000 acres of timber at least thirty
years old. and the fencing Of railways
represents 8l5, 900. 900. and the annual
repair $l5.OOO,OOO These are but
moiety Of what is required Of our forest
